Hydra is a Python framework for elegantly configuring complex applications through dynamic, hierarchical configuration composition. It allows overriding configuration from the command line and running multiple jobs with different arguments from a single command.

Use cases

• manage complex application configuration in python
• compose hierarchical yaml config files
• override config values from the command line
• run parameter sweeps for machine learning experiments
• add command line tab completion to a python app
• launch multiple jobs with different arguments
• avoid boilerplate config loading code

When to choose

• you have a complex application with many configuration options
• you run research or ML experiments needing many config variations
• you want config composition from multiple yaml sources with CLI overrides
• you want to reduce boilerplate around config loading and CLI flags

When to avoid

• you have a simple app with only a few settings
• you need configuration management for infrastructure rather than applications
• your project is not in Python
